“It was quite an extensive operation. It took a little over an hour to get to the patient due to the terrain and rocks,” he said.

The hiker, who officials said was believed to be from Frederick, Md., suffered minor injuries after reportedly slipping and falling while traversing rocks on the trail, and she was taken to Jefferson Medical Center for treatment.

Cogle said rescue personnel from Jefferson County; Washington County, Md.; Loudoun County, Va; and the National Park Service were involved in the rescue operation. The victim was located on a remote portion of the trail, on a mountain area between Chestnut Hill Road and Westridge Hills.
